How long should one of these last?

Developed a leak over the last couple of weeks so thought i would get the pressure tester on it.

Nothing happening , so turned the heater control to COLD and out it poured.

Brand new genuine unit from the local dealer fitted 20k ago (2010).

Ouch! I've just bought a genuine one for the boot spares locker.

That's a bit early. How many miles on it?

Keep up, Mr Gixer.

Typically last two(ish) years, mine is on its third in four and a half years. Mileage not a factor, as mine have averaged 65k 

[chrisgixer]

Mine, on two cars bought at about 65k, the hbv's both failed at about 85k. Both still clipped onto thier posts, not cable tied or bodged and "appeared" original, no mention of replacement in the vx history. So, from that I guess time isn't to important and they last 80k.

...IF they where original with the car.


Seems to me though, there's little choice but to fit oe. regardless.

[05omegav6]

Nothing in the history of mine to suggest it needing one before I bought it... first replaced at 110k iirc

Maybe the spares stock were a different supplier to the original ones could also be that over time they suffer from the same fate as the headlight adjusters and just go brittle with age... same material perhaps

[Shackeng]

Are the same ones fitted on the TD? Or have I asked this before?

Edit: Apologies for hijack.

Acquired the vehicle at 83k in 2010. got it up to scratch inc hbv.

Mileage now just tipped 101k.

I think the internals must perish regardless of being in service.

I suppose there's no choice but to replace like for like.

I will have a look at the new unit to see if there's any sign of manufacture name or production date.

[Andy B]

Mine's on its third in the 11 years I've had the car ..... I assume it had itsoriginal when I bought it, theres 179k on the clock  OE both times I've changed it.

Nope. Part # 90566948

[TheBoy]

Changed the MV6's one once. Before my time, looking at its history, nothing. So looks like 1 in 210k/16yrs.

[TheBoy]

Had one fail on the TD as well, hardly surprising given the coolant issues. Other than that, not done any others on my cars.
